AUTOMATIC SKETCHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 669,857, dated March12, 1901.

Application tiled June 25, 1900.

To all whom it may concern:

Beit known that l, LOUIS RIEBE, a citizen of the United States, and aresident of Lansford, county of Carbon, and State of Pennsyl- Vania,have invented certain new and useful Improvements in Automatic SketchingApparatus, of which the following is a specilication, reference beinghad to the accompa nying drawings, forming a part thereof, in whichsimilar letters of reference indicate cor responding parts.

This invention relates to automatic sketching apparatus and embodies anautomatic sketching device and awheeled vehicle on which said device iscarried and performs its operation.

The nature and objects of the invention will be fully understood fromthe following general description and the annexed drawings and will besubsequently pointed out in the claims.

Figure 1 is a plan view of the vehicle inverted, showing a part of themechanism. Fig. 2 is a side view in elevation of the same. Fig. 3 is asectional view in elevation taken on the line y of Fig. 2.

This sketching apparatus has been devised to automatically delineate ona comparatively small scale the path traveled by the vehicle.

Referring to the drawings, which are hercby made a part of thisspecification, A designates the body of the vehicle, a c the axles, andB B' the wheels on which it is mounted. Two revoluble sleeves(designated by H) ex tend vertically upward from beyond the bottom intothe bed of the vehicle. In the bed the upper end of each sleeve isformed into a bracket H' H2 H', which turn with said sleeves. On thebottom end of these sleeves are mounted the segmental spur-wheels C andC', meshing together. Through these sleeves and beyond either endthereof extend the shafts e2. On the bottom of these shafts are mountedthe bevel-wheels e and f Upon the upper ends of these shafts are mountedthe bevel-wheels g, meshing into the bevelwheels h2. These wheels h2 aremounted on the shafts h, which are journaled in the brackets H I-I2 H.On these shafts are also mounted the wheels h', two on each shaft, onenear each end. They are furnished with sharp conical teeth,asillustrated. The shafts Serial No. 21,603. (No model.)

t' and t" are journaled in suitable bearings attached to the body A ofthe vehicle. The shaft c' carries the wheel e, meshing, respectively,into the wheels f and e. The shaft il also carries the twosheave-pulleys b' and Z22, one, b', in line with the sheave-pulley b onthe hub of the wheel B, the other, b2, in line with the sheave pulley b3on the shaft Z. These four pulleys are connected by suitable belts c c.Two bars d d pivotall y connect the segmental spur-wheel C with the foreaxle ct'. G designates a platform resting on suitable supports in saidbody A, engaged by the teeth of the wheels h' and movable upon itssupport P. F designates a sheet of paper spread on the platform G. Apencil (designated by E) is adjustably held in the hub E2 by thethumb-screw E5. The hub F.2 is held in its position by the curvedbracket E'.

All the several parts of the apparatus are to be substantially asillustrated in the drawings.4

When all the various parts of the device are in theirproper places, asillustrated, if the vehicle be moved motion is transmitted from the hubof the wheel B through the mechanism to the wheels h', which engage theplatform G. If the vehicle be moved in a straight line, the shafts h andh will remain parallel to each other and parallel to the fore axle. Inthat case the platform G will be moved by wheels 71, backward in astraight line, and a straight line will be inscribed on the paper Fbythe pencil E; but if the vehicle be moved in a curve the fore axle,deflecting, and by reason of the bars d, turns the segmental wheel C',and it turns the segmental wheel C, meshing with it. This by reason ofthe mechanicalconstruction described causes the shafts h and h to assumea position at angies with each other, turning with them the platform Gout of a straight line as far as they go. -This causes the pencil E todescribe a curve on the paper F. If the vehicle pass through an entirecircle, a circle will be inscribed on the paper, and if at any time thevehicle while describing a curve returns to a straight line the pencilwill again inscribe a straight line on the paper, and thus the apparatusautomatically delineates the path of the vehicle. The scale of the draftmay be changed by exchanging the wheel l) for pul- IOO leys of differentdiameters,vvhich Will increase or decrease the speed of the wheels inthe sketching mechanism as these substitute pulleys may be larger orsmaller and so increase or decrease the length of movement of theplatform Gin proportion to the distance traveled by the Wheel B.

Having thus described my said invention, What I claim as new, and desireto secure by Letters Patent, is-- l l. The combination with a vehiclecomprising a body and supporting axles and wheels, of a train. of Wheelscomprising horizontal shafts journaled on said body, bevel-Wheelsmounted on said shafts, vertical revoluble sleeves journaled in saidbody, segmental Vwheels meshing together upon the lower ends of saidsleeves, and brackets upon the upper ends thereof, and turningItherewith, vertical shafts revolving in said sleeves bevel-wheels on thelower ends of said Vertical shafts engaging the bevel-Wheels on saidhorizontal shafts and bevel-wheels on the upper ends of said verticalshafts, horizontal shafts journaled in said brackets, bevel-Wheels onthese horizontal shafts engaging the Wheels on the upper ends of saidvertical shafts, and sharptoothed Wheels mounted on said last-namedhorizontal shafts, a movable platform snpported upon the said body ofsaid vehicle, and engaged by said sharp-toothed Wheels, a paper on saidplatform, a pencil adj ustably held with its point on said paper, meanssubstantially as specified for actuating said train of wheels, and meanssubstantially as described for holding said pencil, all substantially asand for the purpose set forth.

2. The combination with a vehicle comprising a body and supporting axlesand Wheels, of a train of wheels, comprising horizontal shafts journaledon said body, bevel-wheels mounted on said shaft-s, vertical revolublesleeves journaled in said body, segmental Wheels meshing together on thelower ends of said sleeves, and brackets upon the upper ends of saidsleeves and moving with them, bars connecting one of said segmentalwheels with the fore axle of said Vehicle, vertical shafts revolving insaid sleeves, bevel-Wheels on the lower ends of said vertical shaftsengaging the bevel-Wheels on said horizontal shafts, and bevel-Wheelsupon the upper ends of said vertical shafts horizontal shafts journaledin said brackets, bevel-Wheels on these horizontal shafts engaging thebevel-Wheels on the upper ends of said vertical shafts, andsharp-toothed Wheels mounted on said lastnamed horizontal shafts, amovable platform supported upon said body of said vehicle, and engagedby said sharp-toothed Wheels, a paper on said platform a pencil heldwith its point on said paper, means substantially as specified foractuating said train of Wheels, and means substantially as described forholding said pencil, all substantially as and for the purpose set forth.

3. The combination with a vehicle comprising a body and supporting axlesand Wheels, of a pulley on the huh of one of said supporting-wheels, atrain of Wheels comprising horizontal shafts journaled on said body,pulleys on said shafts connected together and to said pulley on said hubof said supporting- Wheel, by belts as specied, bevel-Wheels mounted onsaid shaft, vertical revoluble sleeves journaled in said body, segmentalWheels meshing together on the lower ends of said vertical sleeves andbrackets upon the upper ends of said sleeves and moving with them, barsconnecting one of said segmental Wheels with the fore aXle of saidvehicle, vertical shafts revolving in said sleeves, bevel- Wheels onthelowerends of said vertical shafts engaging the bevel-Wheels on saidhorizontal shafts, and bevel-Wheels upon the upper ends of said verticalshafts, horizontal shafts journaled in said brackets, bevel-wheels onthese horizontal shafts engaging the bevel-Wheels on the upper ends ofsaid vertical shafts, and sharp-toothed Wheels mounted on saidlast-named horizontal shafts, a movable platform mounted on said body ofsaid vehicle, and engaged by said platform, a pencil held With its pointon said paper, a bracket a hub on said bracket, and a thu mb-screT insaid hub, adjustably holding said pencil all substantially as and forthe purpose set forth.

In testimony that l claim the foregoing as my invention l have signed myname, in presence 'of two Witnesses, this 14th day of June, 1900.
